European Ammonites Need Id's


Shamalama

Recommended Posts

I recently purchased a large lot of Ammonites/Belemnites labeled as being from France and I'm hoping some of our European members might be able to tell me what genus/species they are. The only info I have is this: "provenance france département du Doubs 25". I believe they are all Jurassic in age based on the presence of pyritized Pleuroceras in the lot. I was able to separate most of them into a few similar looking groups and the pics are below. Any suggestions are appreciated!

Hi Shamalama,

I don't know any ammonite site in Doubs, France, but this department is far from my region. Some of them look like pyritised, and other not... Perhaps they don't come from the same area.

Hello Shamalama,

the left one and the one in the mid which can be seen on the first photo seem to belong to the genus Amaltheus (subnodosus).

They are liassic ammonites (Upper Pliensbachian). With a little incertitude because of the little dimensions of the ammonites.

These are only the inner whirls of the ammonite shell...

Best regards
